dhyāyantam — meditating; ekam — alone; āsīnam — sitting; puruṣam — on the Supreme Personality of Godhead; prakṛteḥ — to material nature; param — transcendental; śuśrūṣantam — rendering menial service; gurūn — to His elders; kva api — somewhere; kāmaiḥ — desirable; bhogaiḥ — with objects of enjoyment; saparyayā — and with worship.
Somewhere He was sitting alone, meditating on the Supreme Personality of Godhead, who is transcendental to material nature, and somewhere He was rendering menial service to His elders, offering them desirable things and reverential worship.
Śrīla Prabhupāda comments: “Meditation, as recommended in authorized scripture, is meant for concentrating one’s mind on the Supreme Personality of Godhead, Viṣṇu. Lord Kṛṣṇa is Himself the original Viṣṇu, but because He played the part of a human being, He taught us definitely by His personal behavior what is meant by meditation.”
This activity of meditation indicates the brāhma-muhūrta, the early morning hours before sunrise.
